Metformin and pregnancy: what we know
Pregnancy and breastfeeding are special periods where every medication choice deserves careful review. Metformin (Metformin) is no exception. The prescribing information for Metformin provides specific guidance, and the right decision depends on the indication, alternatives, gestational stage and the woman's overall medical picture.
Pregnancy safety data for Metformin
According to the prescribing information for Metformin, the available human data in pregnancy may be limited, supportive, or restrictive depending on the molecule. Some Biguanide agents are routinely used in pregnancy when needed; others are avoided. The risk-benefit calculation includes the importance of treating the underlying condition and the consequences of leaving it untreated.
Breastfeeding considerations
Breastfeeding considerations are usually separate from pregnancy considerations. Some active ingredients pass into breast milk in negligible amounts; others are present at levels that warrant caution. Metformin's principal effect is to suppress hepatic glucose production by inhibiting mitochondrial complex I, which raises the cellular AMP/ATP ratio and activates AMP-activated protein kinase. The prescriber weighs the benefit of breastfeeding, the importance of Metformin, and the availability of alternative therapies.
